XML Viewer & Formatter
Format, validate, minify, and inspect XML documents in a browser-based tree viewer with namespace and node inspection.
Use this free XML viewer and formatter to clean, validate, and inspect XML documents in your browser. Paste XML or open a local file, then format with two or four space indentation, collapse empty elements, preserve XML declarations, and minify for size comparison. The tree view shows every element, attribute, and namespace prefix with click-to-copy path support. No XML is sent to a server. Useful for developers working with SOAP messages, RSS/Atom feeds, Maven POM files, and XML-based configuration.
